For attaining moksha salvation there was never a mantra. For practicing celibacy, for eradicating traces of Prarabdha karma we definitely have two mantras but not more.
Practicing celibacy mantra and Prarabdha mantra I finally succeeded reaching state of self realization, god realization and moment I leave my mortal frame, I shall attain moksha salvation.
With my own experience I can confidently say there is no mantra to attain moksha whatsoever.
Everything in field of spirituality demands curtailing karma to zero, only then we could remove dross impurities within our soul atman. Spiritual journey was all about a soul atman regaining its lost original pure prime pristine primordial form. This becomes possible when indulging in spirituality detailed in Bhagavad Gita human beings became a pure soul atman forever.
For a soul atman to reach state of absolute purity, guidance from Lord Krishna at each and every stage of spiritual life is necessitated. Dominated by a bloated ego we could not hear voice of Lord Krishna coming from within our heart.
Do not know what happened around six years of age I became 100% truthful. So much so that I could distinctly hear dictates of Lord Krishna coming from within my heart and started my spiritual quest of life. My ego when six years of age was zero might be from previous birth.
Indulging in spiritual precepts of life contained in Bhagavad Gita I realized that to reduce dross impurities within my soul atman I had to establish total control over five senses and mind. And started my pursuit of reducing desires and wishes at a rapid pace so that I could establish total control over mind power!
I took almost 22 years, around 28 years of age I succeeded overpowering five senses but control over mind power was still afar. I was now closer to God than ever.
Practicing absolute celibacy for 14 years in continuation I finally succeeded in full awakening of kundalini shakti, activating my brain to full 100% capacity. About 31 years of practice of spirituality detailed in Bhagavad Gita I finally reached God in the wee hours of third of August 1993 at 37 years of age.
That was the moment I had a lengthy above two hours Sakshatkar with God. The experience was out of this world. It was around 4.15 a.m. in the morning when God Almighty started his dictation. It was then I came to know that as a soul atman my journey has ended. I had reached 8.4 millionth manifestation. Also my kundalini had awakened fully absolutely unknown to me.
In present Kali Yuga it is difficult to indulge in spirituality for the only reason that glitter of material world does not let us overpower five senses and mind. Furthermore beautiful girls galore all around do not let a seeker practice absolute celibacy, what to say of 14 years in continuation.
Practice of celibacy is necessitated for full awakening of kundalini shakti, the coiled Serpentine energy lying dormant in base of spine. Only then our brain activates fully 100%.
